Humans are capable of discovering and creating great things with the help of science and one such impressive discovery is that green, living plants can generate electricity. It may seem unbelievable, but not impossible.

One must be wondering how this technology works. Well, the answer is quite simple; photosynthesis. Plants excrete organic matter into the soil as a result of photosynthesis. Only some of the organic matter is used by plants and the rest is released in the soil. This released organic matter is broken down by bacteria. In the breakdown process, electrons are released as a waste product. Since the movement of electrons produces electricity, these electrons, which are of no use to the plant, can be harvested. The best part about this innovation is that the plants from which energy is being generated are not affected in any way.

This idea was first put into use by a Dutch start-up called Plant-e. This company was launched in September 2009 and is successful in launching and selling many environment- friendly products like DIY kits to the public for experimentation purposes and modular systems which could be easily installed on green roofs for abundant electricity production. Plant-e is involved in various projects, within The Netherlands, like automatic lighting systems in gardens and many more.

This technology works with the plants which thrive in moist soils and where the water is present in abundance. Therefore marshlands, paddy fields and deltas are some of the most suitable places for setting up plant batteries as a huge amount of water is present in those areas. Hence, the use of this technology is limited to certain geographic areas containing moist soils and cannot be used in arid regions. It may, however, promote the growth of more trees and plants which will gradually reverse the malicious effects of global warming.

Another obstacle in widespread adoption of this technology in today’s time is the high cost of installation of the system. The initial adopters of this technology are those who are attracted by the efficiency and eco-friendly nature of the plant batteries and willing to pay a premium for it.

The concept of plant batteries can be further taken into rural areas where most of the population still does not have access to adequate electricity. It is estimated that plant-MFC technology can cover upto 20% of European Union’s primary future electricity needs. Also, plants are almost 100% efficient at converting photons from sunlight into electrons which indicates a bright future for this technology. However, more research needs to be done in this field.

Another innovation in the field of green electricity is using algae , which often grows in ponds and rivers, for generating electricity. The basic concept which explains the working is similar to the way plants are able to produce electricity; photosynthesis.

Various other ventures in the field of renewable energy also include vegetable batteries, meaning, electric power generated from fruits and vegetables like lemons, tomatoes and potatoes, have been investigated. According to experiments, at least 3 to 4 vegetables are required just to light a small LED bulb. Moreover, it leads to poisoning of the vegetables and those food products need to be thrown away, without being useful for consumption purposes. It is therefore not a viable option for energy production.

Plant based electricity generation is still an evolving technology which has immense potential for producing energy in an environmentally sustainable way. It will realise full potential when the installation cost is attractive enough for the farmers to prefer it over the electricity grids or fossil fuel based personal electricity generator sets.

Bengal Elections: Will there be a transfer of power or TMC’s will rule continue?

As the assembly elections in West Bengal are getting closer, the competition between the Bharatiya Janata Party (BJP) and Trinamool Congress (TMC) is getting more intense. This election and its result will  be historic. Whole nation is looking forward to the Bengal Elections keenly.

Recently, there was a lot of hue and cry by the BJP when some people allegedly tried to attack the BJP party president JP Nadda's convoy near Diamond harbour in West Bengal. While the BJP labelled the attack as a “sponsored violence”, CM Mamata Banerjee called it a “drama” staged by the BJP to gain media attention. But apart from all this, there are other things which make this election important.

Other than the BJP and the ruling TMC, there are other players as well – Left Front, led by CPI(M), Congress Party, AIMIM.

The situation of the Left Front and the Congress

In the 2019 Lok Sabha elections, the Left Front did not win a single parliamentary seat. Also, except the Jadavpur constituency, it lost all its deposits in all the seats. The Indian National Congress, which is its alliance partner, did not fare well as well and managed to get two seats only. In the upcoming 2021 assembly elections, the two parties have again joined hands, and this time, it’s not just about the electoral victory, but also about maintaining their relevance in the state.

The Left Front, which used to be a major party in the state and ruled for decades, is now seeing an existential crisis. Their first aim is to retain themselves as the main opposition party of West Bengal. Mamata Banerjee’s thumping victory in the 2011 elections marked the end of the Left rule in West Bengal. In the 2016 Assembly Elections, Trinamool Congress had a landslide victory, whereas the BJP got only two seats. But now, the BJP is emerging as the main opposition to TMC, which should be a matter of concern for the Left Front which is losing ground. In an article by The Quint, CPI(M) leader Shatarup Ghosh said, “Of course the BJP is our main opposition—not just in West Bengal but also nationally. They are ideologically and politically completely opposed to us. But that being said, we are not ready to give an inch to Mamata Banerjee either. The TMC needs to go, but they can’t be replaced by the BJP. That is our position”. The Left also alleges that TMC violence against them increased especially after 2016. “At this point, because we couldn’t function in full strength, there was a void in the space of the opposition. The BJP came in at that point and said that they’re running the centre, have CBI, ED and other machinery and can help fight the TMC in a way that the Left can’t. Those who wanted to vote against TMC, therefore, naturally went to them”, he adds.

The Indian National Congress has ruled West Bengal first from 1947–62, and then again from 1972–77. After that, Congress has not performed well in the elections here.

Rise of AIMIM in West Bengal

All India Majlis-e-Ittehad Ul Muslimeen– better known as AIMIM, has seen a rise recently outside their home state, after winning 5 seats in the Bihar elections. Party President Asaduddin Owaisi held a meeting with AIMIM West Bengal party functionaries for taking their views with regards to the upcoming elections and political situation in the state, calling it a “fruitful” meeting.

On AIMIM focusing on Bengal Elections, TMC MP Saugata Roy took a jibe at the party’s chief and called him “an assistant of the BJP, who is being used by the latter to split non-BJP votes”.

Muslim votes are crucial for the TMC. AIMIM senior leader Syed Asim Waqar tweeted, telling Mamata Banerjee’s party that their enemy is the same, the BJP. Aurangabad MP and AIMIM Maharashtra President Imtiaz Jaleel tweeted: "Bihar tou jhaaki hai...WB, UP baaki hai" (Bihar is just the beginning, West Bengal and Uttar Pradesh are remaining). Other than this, party chief Owaisi recently said that it has been the consistent stand of the party that it would not contest elections in Assam and Kerala, as AIUDF and the Indian Union Muslim League are present in the two states. These points clearly show which states the party is aiming for.

AIMIM rallies had also gathered large crowds in Bihar. It won 5 seats in the Seemanchal region of Bihar, which borders West Bengal. It is also trying to emerge as the voice of the Muslims in states like West Bengal and UP. AIMIM was part of the Grand Secular Democratic Front, that had two UP based parties—Bahujan Samaj Party(BSP) and the Suheldev Bhartiya Samaj Party (SBSP)—besides Samajwadi Janta Dal and Rashtriya Lok Samta Party (RLSP). Owaisi's party was the best performer among all of them, other than that only BSP managed to get one seat.

Muslims in West Bengal

Muslims form about 27% of the West Bengal state population, but still remain underrepresented. They account for only 6% of government jobs. Although their representation has been better under the TMC, they still need improvement in the representation for the betterment of their community.

BJP and TMC

Recently, TMC MLA Suvendu Adhikari—along with 23 others—joined BJP, at Home Minister Amit Shah's Midnapore rally, as a major blow to Mamata Banerjee and the TMC. Shah alleged that Mamata Banerjee has changed her party’s slogan from “Maa, Maati, Manush” (Mother, Earth, Humanity) to “extortion, corruption and pandering to the nephew”, targeting Banerjee’s nephew and MP Abhishek Banerjee.

The BJP increased its seats from 2 to 18 in West Bengal in the 2019, which came as a surprise. Almost 57% of Hindu votes went to the BJP, and 32% to TMC. The party is trying to woo Hindus and also the Hindi-speaking population of West Bengal. Recently, BJP-supported Hindutva organisations such as the VHP, Bajrang Dal and the RSS, which had only a little presence in the state, have become more assertive, as was seen through their armed processions for Ram Navami.

To keep a check on the saffron party’s rise, the Mamata government made sure to announce new schemes and that the previously implemented policies remain fresh in the minds of the people. Recently, the TMC released its 'report card' on the work they have done and the promises kept. They have mentioned the 'Sabujsathi' scheme in it, which, according to the Mamata government, has been fulfilled. In this scheme, bicycles were to be distributed among approximately 40 lakh students from classes 9th to 12th studying in govt run and govt aided schools in West Bengal. The scheme was launched in September 2015. A scheme called “Swasth Saathi” was launched recently by the West Bengal government, as the BJP attacked the government by saying it did not implement the Ayushman Bharat scheme of the central government.

Even after opposition from newly emerging parties in the state, like the BJP and AIMIM, other than that from the already existing parties, the Left Front and the Congress, the TMC is trying to remain optimistic about their third term. Who’s winning? Only time—and the people of West Bengal—will tell.
